SCHUBBER OR BRUSH.

Specification of Letters Patent.

Patented April 17, 1906.

Application filed March 30, 1905. Serial No. 252,833.

To all whom it may concern.-

Be it known that I, AXEL THOLLANDER, a citizen of the United States,residing at Chicage, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Scrubbers or Brushes, of whichthe following is a specification.

This invention relates to scrubbers or brushes, and is particularlyillustrated and described in connection with a windowcleaner, embracingimprovements with respect to the construction of the cleaner and alsowith respect to the handle and the means to attach the same.

With respect to the handle attachment a ball-and-socket joint isprovided which has means to insure its rigidity when desired, whilepermitting adjustment to vary the angle at which the cleaner ispresented.

In the accompanying drawings, Figure 1 is a plan view, partly insection, of the cleaner. Fi 2 is a side view with parts in section. Fig.3 is a plan view showing the ball of the ball-and-socket joint. Fig. 4is a sectional view showing one of the socket-arn1s which connect theball to the head of the scrubber.

Referring specifically to the drawings, 6 in dicates one metal strip,and 7 another metal strip, between which the rubber strips 8 of thescrubber are clamped by means of bolts 9. The strip 6 has at the rearedge thereof a flange 10, which extends over the space between thestrips and serves as an abutment for the rear edges of the other strips.

A socket-piece to receive the handle of the device is indicated at 11,and this has at the front end a ball 12, which is provided with severalpointed lugs or projections 13. 14

indicates arms secured to the scrubber-head by the bolts 9 andterminating at the rear end in sockets 15, made to fit on opposite sidesof the ball 12 to form a ball-and-socket joint, which turns on apivot-bolt 16, extend ing through the parts. The pivot-bolt is providedwith a wing-nut 17, so that it may be loosened when desired. Theprojections 13 are arranged to fit in notches 18, formed in the sockets15, to hold the parts at the desired angle or adjustment. \Vhen the nut17 is loosened, the arms 14 may be sprung apart far enough to allow theprojections 13 to pass from one notch to another, and so vary the angleof the scrubber-head with respect to the handle as desired, after whichthe parts are fixed at adjustment by tightening the nut 17. The fit ofthe lugs 13 in the notches 18 prevents any unintentional or accidentalslip at the joint.

What I claim as new, and desire to secure by Letters Patent, is

A handle-fastening for scrubbers and the like, comprising a socket-piecehaving a globular head with projecting lugs thereon, arms secured toopposite ends of the scrubber and converging to said head and havingconcave sockets fitting opposite sides thereof and notches in saidsockets to receive the lugs, and a pivot-bolt extending through thesockets and the head.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

AXEL THOLLANDER.
